Wheel.



pNrTED STATES Barnier ormone CHARLES nxsonwaaz, or rtunisini:prima, PENNs'LvAniAI f y,

Be it known that I, CHARLES L. SCHWARZ, a citizen of Vthe United States, residing in the city and` county ofPhiladelphia, State of Pennsylvania, have invented a new and useful Wheel, of 'whichI the following is a specification. A

My invention consists'of improved means for taking up any shrinkage which may take place at the joint. between the rim and spokes of a wheel. f

It furtherconsistf if improved-means for taking up shrinkage of the rim of thewheel.

It furtherconsists' of other novel features of construct-ion, allas will be hereinafter 4 fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at pres- 1 ent preferred by me', since the same has been found in practice to give sat-isfactoryand.

reliable results, although it is to be under. stood that'the various instrumentalities 'of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of .these instrumentalities as herein shown and described.`

by: means of which. the wedges may be drawn into the wedge-shaped openings beeo'ftween the beveled ends of the felly sections to expand the same tightly-against the tire.

Blocks, 6, are secured 'by means of .screwbolts, 7, having nuts, 8, passed through the .tire and felly sections, and through perfo. rated ears, 9, upon the blocks.. Said blocks have grooves, 10, transverse to the felly sections andformed with inclined bottoms, and

each block-has perforated lip, 11, projecting at the shallow end of the groove.v The `outer ends of the spokes, 18, have open fer-k rules, 12, and said ends, 13, are out inclined to correspond to the inclined grooves, the ferru-les being eut or notched, at 14, at the ends ofthe inclined faces of the spokes. Wedges, 15, are placed to have their inclined sides' bear against the inclined bottoms of lthe grooves and the, inclined facesof the spokes, and screw-bolts, 1G, vpass through .longitudinal bores in said wedges, and their threaded ends project` through the narrow end 4of the wedges and through. the perfo- V sof rated lips of the blocks, and'nuts', `17, fltj' upon the threaded endsl and bea-rl against '5 the perforated lips to draw the wedges `into l blocks and the fi; i

their wedge-shaped seats. The grooves 10 in the grooves formed by the inclined ends 13 of the spokes and the notches 14 in'tlie ferrules Y are dovetailed, and the sides of the wedges ,are correspondingly dovctailed, so that the "wedges will be retained in placev between the blocks and the spokes and said parts will beheld together bythe wedges.

By. means of beveled ends of the felly sections, the rim thel wedges between' theV may be expanded if the wood in the felly sections shrinks, and if the spokes shrink,

such shrinkage ing the wedges upon the 'felly sections and the inclined ends of the spokes.

4may be taken up by draw-v inbetween the blocks or seats p will be further apparent? that by my invention, thel tellyl sections canibe removed from the spokes in case it isidesired to change the tires, and another tire .1 .5
